Simulation recording add 10 pixal padding around application area, Cap 8

I am  recording a new software simulation using application with a Snap to, Custom Size of 1280 by 893. Usually this resizes the application to the custom size but for some reason the application snaps to a size that is slightly smaller than the capture area. Thus the simulation includes about ten pixels to the sides and bottom of the application. This happens to every application, no matter the browser, or application type. Is this a bug? Is there a fix (not a work around)?

OS is Windows 10. I have the app size in the display setting set to 100%. Is there any other Win 10 setting that could be causing the problem?

Any help is greatly appreciated!
